Jetting specs.
« on: August 13, 2013, 09:55:15 pm »
Does anyone have a good starting point for jetting a 36mm VM Mikuni on a TM400 Suzuki. The motor has blueprint port work, full circle rank and standard ignition with extra 2kg weights.
I bought  new 36mm to replace the 34 that was on it so I'm starting from scratch.

Phew I'd have to look but either a 60 or 65 pilot, the needle from the TS standard carb(fairly lean) and around a either 280 or 380 main.
